The freezing point of a CaCl2 solution is -24 ∘C. 1.What is the molality (m) of the CaCl2 solution? 2.What is the boiling point of the CaCl2 solution? Hydrochloric acid (HCl) reacts with sodium carbonate (Na2CO3), forming sodium chloride (NaCl), water (H2O), and carbon dioxide (CO2). This equation is balanced as written: 2HCl(aq)+Na2CO3(aq)→2NaCl(aq)+H2O(l)+CO2(g) 3.What volume of 1.75 M HCl in liters is needed to react completely (with nothing left over) with 0.250 L of 0.500 M Na2CO3? 4.A 501-mL sample of unknown HCl solution reacts completely with Na2CO3 to form 12.1 g CO2. What was the concentration of the HCl solution?. 1.What is the molality (m) of the CaCl2 solution? 2.What is the boiling point of the CaCl2 solution?

The freezing point of a CaCl2 solution is -24 ∘C.1.What is the molality (m) of the CaCl2

solution?

2.What is the boiling point of the CaCl2 solution?

Hydrochloric acid (HCl) reacts with sodium carbonate (Na2CO3), forming sodium chloride (NaCl), water (H2O), and carbon dioxide (CO2). This equation is balanced as written:

  • 2HCl(aq)+Na2CO3(aq)→2NaCl(aq)+H2O(l)+CO2(g)

3.What volume of 1.75 M HCl in liters is needed to react completely (with nothing left over) with 0.250 L of 0.500 M Na2CO3?

4.A 501-mL sample of unknown HCl solution reacts completely with Na2CO3 to form 12.1 g CO2. What was the concentration of the HCl solution?
